What's the reasoning of adding a backing solenoid to boat trailers???? Why did the trailer manufacturers decided to install one??? The slightest corrosion on the trailer or towing vehicles plug will not activate the solenoid, sometimes backing up a slight incline will cause problems.
Another post about trailer lights to unplug before launching, it'll never happen with a "Five Flat Plug" :confused:
